Test strategy before shipping:
(1) Vi = 0V => ADC < 20
(2) Vi = 0.8V => ADC > 25
(3) Vi = 3.2V => ADC < 248
(4) Vi = 4.4V => ADC = 255
(5) 0.8V < Vi < 3.2V, 25 points (step 0.1V) will be tested. All test points should be recognized
correctly.
Comment:
a. (1) guarantees 0V input can be recognized (ADC value < 20).
b. (4) guarantees 5V input can be recognized (ADC value = 255).
c. (2), (3) and (5) guarantee linear (with 4 bits at least) within the usable range (0.8V to 3.2V).
